Letters Patent No. Hi8/127, dated October 18, 1870.

IMPROVEMENT IN TREADLE MOTIONS.

The Schedule referred. to in these Letters Patent and making part of thename T o all whom li t may concern Be it known that I, ARTHUR M. ALLEN,of the city, county, and State of New York, have invented a new andimproved Treadle Motion; and I do hereby declare the following to be afull, clear, and exact description thereof, which will enable thoseskilled in the artto make and uscrthe same, refer ence being had to theaccompanying drawing forming part of this specication, in which drawing-Figure l represents a front View of this invention,

leasier and less iitigning than that of an ordinary treadle.

.l The toot-peiuliilnins have their t'ulcrnms on a rod supported inbearings, which can be moved toward and from the operator, so that thepedals'attached to said pendnlums can be brought in the requiredposition to suit operators oi' different stature.

Said foot-pendnlnms are made in two parts, connected to each other bypivots 01 hinge-joints, so that the distance between the pedals can bereadily adjusted to suit the convenience ol' the operator.

In the drawinglhe letter A designates a frame, which forms the bearingsfor a shaft, B, in which are formed two cranks d, which are bypreference set in opposite directions, but which may be arranged in anydesirable position in relation to each other.

Said cranks connect by rods b with the upper ends of pendulnms O, to the'lower ends of whiclrarc sc-A cnred pedals which I term oot-pendnlums.

l The fulcrnm of my foot-pendulnlns is on a rod, d, v

which has its bearings in brackets e, that are adjustable on rods f,secured between the legs orside pieces of the i'ame A, being set in therequired position i by set-screws, or any other suitable means.

By these means the pedals can be brought closer to or further from thefront ofthe frame A, and they can be easily adjusted to suit the statureor convenicncc of the operator.

The stroke or amount of motion of the pedals may also be changed bybringingfthc connection of the rods b, with the foot-pendnlnms,'closerto or further from the filler-nin d. The same etect will be produced bychanging the length of' the pendnlums below the fulcrum d.

Said foot-pendulums are made in two parts, which are connected byhinge-joints or pins g, sothat the distance between the pedals can beincreased or decreased to suit the convenience of thc operator.

By thesemeans a treadle motion is obtained which allows of imparting apowerful motion to the crankshaftfrom a sitting position withcompara-tively little exertion, the motion ofthe feet being the same asin walking.

What I. claim as new, and desire to secure by Letters 1atent-,is-

1. The foot-pendnlums C, in combination with the double crank-shaft B,substantially as shown and de' scribed.

2. The brackets c and rods or supports f, in combination with the rodwhich forms the fulcrum of the foot-levers, substantially as set forth.

3. The arrangement of a hinge-joint in thc footpendulums, to allow ofspreading or closing up the pedals, as described.
